To aZZ fr0/wm, t may concern:

Be it known that I, JAMES W. ScHNnmns, a. citizen of the United States, residing at Tacoma, in the county of 'Pierce and State of Washington, have invented a new and useful Edge Trimmer and Burnisher for Shoe-Soles, of which the following is. a. specification'.

This .invention relates to machines used `in making or repairing shoes and especially to machines for trimmingand burnishing the edges of shoe soles, and has4 for its object to provide a machine which will be adjusted whilethe machine is in mot-ion for any thickness of the sole leather` .I att-ain this and other objects by the de vices, mechanism, and arrangements illus trated in the accompanying drawings, in which- 'Figure l is a plan of the machine, the cover thereof having been removed. to reveal the interior, and showing the 'burnisher withdrawn and the trimmer extended for use; Fig. 2 is a similar view of the trimmer end of the machine in its. withdrawn position, and Fig. 3 shows the burnisher end in its extended position; Fig. 4 is a horizontal longitudinal section of the machine with the parts in the same position as shown in Fig. l; F ig. 5 is an-end elevation of the trimmer end of the machine; and Figs. 6 and Z are perspective views of the shifting collars of the outer and inner tool shafts respectively.

Similar numerals of reference refer to similar parts throughout the several views.4 This machine is provided with a suitable standard on which the hase plate or frame 1 is mounted, said frame being provided with a series of suitable bearings 2, all said bearings being coaxial. A hollow shaft, or carrier, 3 is mounted in said bearings to turn therein and is provided with a suitable pulley 4, driven by the belt 5, in the usual manner. The carrier 3 is provided, with oups or enlargements 6 and 7 at its ends, adapted to receive the trimming tool and the burnishing tool respectively when they are withdrawn om operating position. The carrier 3 is slotted, as at 8, said slot eX- tending diametrically entirely through the lcarrier and being parallel with the axis thereof. The pulley 4 is mounted between.

two of the bearings 2 so that the carrier cannot move axially Ain .the bearings.

Within the rotating carrier 3 is mounted e Ihollow. tool shaft9,-which is free to move vin the hollow tool axiallywithi-n the carrier 3 but which rotates therewith. This tool shaft 9 is slightly longer than the carrier 3 and carries a burnishing surface 10 at one end and a trimming tool 11 at the other end, with a rotating guard 12 immediately outside of said trimming tool ll.

The trimming tool consists of a number of Vteeth arranged around its cylindrical surface parallel with its axis, which teeth inter-l mesh with the inclined edge-teeth on the end of the cup 6.`

tool shaft 9 is rotated by` the carrier 3 through the sliding connection eifected by the pin 13 which passes through the shaft 9 and slides in the slots 8 ofthe carrier and which issecured in a loose collar 14 surrounding the carrier 3. This collarv 14 rotates with the carrier 3 but is free to slide axially thereon and to carry the tool shaft 9 therewith, but its axial motion is controlled by the. bifurcated collar 15, one portion thereof being on each side of the rotating collar 14. This collar 15 does not rotate but. is formed in one piece with the casting 16 which is slightly above the axis of the collar,said casting being providedlwith a compound notch in its edge. The outer portions 1T of this notch are similar and are formed of two ports of a circular arc each part having as center the center of the pivot of the actuating lever when the said casting 16 and collar 15 has been shifted to the two extremepositions, and the center part 18 of the notch, between the two parts 17, is curved and is deep enough for the said actuating lever to engage it when it is in intermediate position. The tool shaft 9 is also provided with two slots 19 passing diametrically through it, one slot being on each side of the portion through which the pin 13 passes.

The central tool shaft 20 is mounted withshaft with but has an additional axial motion relatively thereto. This tool shaft 2O carries e, small burnishing surface 2l at one end and a small trimming surface 22 at 'the other end. This shaft 20 is very longer than the shaft 9. The shaft 20 is rotated by the carrier 3 by means of two pins 23 which are securedin the shaft 20 but which pass freely through both the slots 19 andiS'fand are securedin the two loose- Colorear V@unourrit.ng wfrrier 3, L

9 and rotates there.

slightly The outer end of the burnishing tool' is slightly upset as shown. TheV in the casting 16 to move collars 2% rotate with the carrier 3 but are free to slide axially thereon and to carry the inner tool shaft 2O therewith, but their axial motion is controlled by means of the shitting mechanism comprising the two collars 25 formed on a vsingle casting 26 and each adapted to engage the inner sides'ot the loose collars 24. The casting 26 has a rack of teeth 2'? the collars 25. The casting 26 slides on the base plate or frame 1 and does not rotate. The shaft 2O has a slot 2S therethrough through which the pin 13, above described, freely passes. Thus it will be seen that both of the tool shafts 9 and 20 rotate with the carrier 3 and that each ot them has an independent axial motion therein.

The operating lever comprises a handle 29 acting in a horizontal plane about a pivot 30 and having a toothed sector 31 engaging and operating the rack 27 and a roller or lug 32 engaging the part 18 of the notch the casting from its mean position but engaging" the parts 17 of the notch to hold the casting in its extreme positions. Springs 33 are secured to the frame and to the casting 16 to resist its displacement from its central position.

The operation of my machine is briefly as follmvs't---The belt 5 rotates the carrier 3 through the jLlley 4. and the carrier rotates both of the tool shafts 9 and 20 through the pins lf3 and 28. lf the sole is of thick leather then, to trim its edge, l turn the handle 29 to the right until the trimming surface 1l extends suiticiently from the cup 6 on the left-hand end of the machine to tit the leather and so that the guard lf2 engages its edge; but it the form of the shoe will not allow theuse of the guard then l turn the handle-Q9 farther to the right so that the tool surface 22 extends beyond the surface 11, said surface 22 having no guard on its outer face; then, to burnish the surface, the handle is correspondingly shifted toward the lett and the corresponding burnishing tools 10 and 21 extend out from the cup 7 on the righthand end of the machine.

Having described my invention, what l 1. ln a shoe-sole-edge liinishing machine, the combination with a trame; of a rotating carrier mounted therein, and having a tool- Gopies e! this patent may be obtained for slightly below the axis of cup at one end thereof; a tool-shaft rotated by said carrier and axially movable relav tively thereto, and carrying a tool on the end thereof" adapted to extend outward from the cup in said carrier; and means t'or axially shifting said tool-shaft whereby the extentthat the tool projects from the cup is adjusted.

2. ln a shoe-sol'e-edge finishing machine, the combination with a trame; of a rotating carrier mounted'therein, and having a toolcup at one end thereof; a hollowtool-shaft rotated by said carrier and axially movable relatively thereto, and carrying a tool in the end thereof adapted to extend out ward from the cup in said carrier; a central t`ool-shaft mounted within said hollow toolshaft and rotatingq therewith but axially movable relatively thereto and carrying a tool at the end thereof adapted to extend outward from the end ot'said tool on said hollow shaft or to be withdrawn thereinto; and means engaging both of said tool shafts and acting,l thereon whereby the extent that the tool on the hollowl tool-shaft. projects beyond the cup, and the extent that the tool in the central shaft projects beyond the first tool, may be adjusted.

3. ln a shoe-sole-edge finishing machine. the combination with a trame; ot a rotating carrier mounted therein and comprising a hollow shaft with a longitudinal slot therethrough and a tool-cup at one end thereof: a tool-shaft mounted withinsaid carrier; a pin secured in said tool-shaft and passing through the slot in the carrier whereby the tool-shaft is rotated by the carrier but is axially movable relatively thereto; a tool mounted on the end ot saidl tool-shaft and adapted to .extend outward from the tool# cup on on said carrier and secured to said pin; an axially movable, nonrotative, collar on each side of said loose collar whereby said loose collar may be shifted onV said carrier; and a pivoted lever mounted 0n the frame and engaging said nonrotative collar to move it axially whereby the extent that the. tool projects from the cup is adjusted. j
